Pyinstaller：moviepy打包报错AttributeError: module ‘moviepy.audio.fx.all‘ has no attribute ‘audio_fadein‘

一、前言

使用到了第三方库 moviepy 本地调试是OK的，
打包运行之后报错了
记录一下分析问题并找寻解决办法的过程

二、问题原因

moviepy下的子包使用的是一种动态加载模块的模式加载包下的模块的
pyinstaller对这种模式不能处理，所以需要我们手动处理一下，将其展开。

三、解决问题方法

1、修改moviepy\video\fx\all_init_.py

修改内容如下：

"""
Loads all the fx !
Usage:
import moviepy.video.fx.all as vfx
clip = vfx.resize(some_clip, width=400)
clip = vfx.mirror_x(some_clip)
"""

import pkgutil

import moviepy.video.fx as fx

__all__ = [name for _, name, _ in pkgutil.iter_modules(
    fx.__path__) if name != "all"]

# for name in __all__:
#     print("from  moviepy.video.fx import %s" % (name))

from  moviepy.video.fx import accel_decel
from  moviepy.video.fx import blackwhite
from  moviepy.video.fx import blink
from  moviepy.video.fx import colorx
from  moviepy.video.fx import crop
from  moviepy.video.fx import even_size
from  moviepy.video.fx import fadein
from  moviepy.video.fx import fadeout
from  moviepy.video.fx import freeze
from  moviepy.video.fx import freeze_region
from  moviepy.video.fx import gamma_corr
from  moviepy.video.fx import headblur
from  moviepy.video.fx import invert_colors
from  moviepy.video.fx import loop
from  moviepy.video.fx import lum_contrast
from  moviepy.video.fx import make_loopable
from  moviepy.video.fx import margin
from  moviepy.video.fx import mask_and
from  moviepy.video.fx import mask_color
from  moviepy.video.fx import mask_or
from  moviepy.video.fx import mirror_x
from  moviepy.video.fx import mirror_y
from  moviepy.video.fx import painting
from  moviepy.video.fx import resize
from  moviepy.video.fx import rotate
from  moviepy.video.fx import scroll
from  moviepy.video.fx import speedx
from  moviepy.video.fx import supersample
from  moviepy.video.fx import time_mirror
from  moviepy.video.fx import time_symmetrize

2、修改moviepy\audio\fx\all_init_.py

修改内容如下：

"""
Loads all the fx !
Usage:
import moviepy.audio.fx.all as afx
audio_clip = afx.volume_x(some_clip, .5)
"""

import pkgutil

import moviepy.audio.fx as fx

__all__ = [name for _, name, _ in pkgutil.iter_modules(
    fx.__path__) if name != "all"]

# for name in __all__:
#     exec("from ..%s import %s" % (name, name))
from  moviepy.audio.fx import audio_fadein
from  moviepy.audio.fx import audio_fadeout
from  moviepy.audio.fx import audio_left_right
from  moviepy.audio.fx import audio_loop
from  moviepy.audio.fx import audio_normalize
from  moviepy.audio.fx import volumex

四、最终结果

打包成功！并且文件体积也没变多大。

打包，最好新建一个新的虚拟环境，然后再在新的虚拟环境安装pyinstaller，再在新的虚拟环境下打包，这样子就会小很多了。
